Bitcoin Forum

Hello guys.

Last night from my BTC address were stolen several coins. I had term with an user here to buy some LTC. The only thing he wanted was to check I have enough BTC to buy his LTC. So I sent 0.01 BTC to his address to show him I have the amount.Several minutes later I watched  outgoing transaction with all my coins from my wallet to the same address I sent 0.01.
My wallet were encrypted!
I checked his address this morning, the coins are still there.
I guess there is no way to recover them, just wanted to protect other users here. Be aware, that was something I have never heard.

Computers are not easily securable.
I am looking forward to this:

Yes, made by Slush, the biggest pool's owner.

Your computer is compromised for sure.

It's already done! I changed HDD!

change harddrive. new wallet as the old one is compromised and either format the old harddrive with a high secure delete software or send it to someone who can have a look at it and maybe maybe track the software that got your coins. you wont get them back byr ir might help others

Is that a pro or a con?

Slush was the guy who came up with the concept of pooled mining and created the first ever pool - I think that's what he meant by biggest.

He's a bit of a living legend, with the attacks on his pool that he's thwarted, and so on.

How was your wallet generated? Bitcoin client fresh install wallet, imported key or other client?

One I made a localbitcoin deal. The seller did not have any device with him. So I gave him my smartphone to execute the order (first time I made a localbitcoin deal). He logged into his account and I was sitting at his side. The deal went OK. But in the evening I saw many tries on my account to open the account - luckily unsuccessful.

My lesson is never to give away any unlocked hardware anymore. And I will not type in any passwords with anybody looking on my fingers for sure.

@Grogorash
You write your wallet was encrypted. I conclude that you use Bitcoin-QT with a local encrypted wallet.dat. To transfer the Bitcoins from your wallet to a new address the thief must have had access to the wallet.dat file and to the password. Maybe was able to inject some kind of trojan software into your system ?

Do you remember the strength of your wallet password. Which kind of security software do you use on your computer to prevent intruder, viruses and malware ? Firewall, virus detector, malware protection, coockie blocker ...

I think it would be important for all of us to analyse this case for fraud prevention in the future.

Goodbye coins  :) ... just if you have a chance, go to him and whoop his ass

If you don't mind, make the information about the thief's address public (and your address). Also describe exactly what you did to transfer the money.

I was just thinking the same thing.

Did he ever had access to you computer? Did you send the 0.01 BTC from his computer? I would suggest to provide more information and post in Technical Support.

"I had term with an user here to buy some LTC",
How he did this I suspect is in the above statement.

Now we can start speculating what he really did.

Second question is why it is necessary to show someone his Bitcoin amount with a small transaction - at that point I would have been mistrustful.

Don't tell us the user's name or anything.
